It's no secret that Swift and Lamar dig each other's music, so it seems plausible to me that they may have teamed up for a "Bad Blood" remix (which would explain Lamar's presence on set)... but what about Delevingne, Zendaya, and Williams? Are they all featured on the (rumored) remix, too? Or are they just appearing in the visual? Your guess is as good as mine, really. "Bad Blood" is about a friendship gone sour, so perhaps Swift just wanted to surround herself with pals she trusts for the music video? We'll have to wait and see.

Check out the "Bad Blood" set pics below.

Taylor Swift

Oooh, I like her hair.

Kendrick Lamar

Socks with sandals was a... choice.

Cara Delevingne

Brow game on point, as usual.

Zendaya

I have to admit, the white robes they were all wearing are weirding me out a little bit.
